Python 我无法使用MatplotLib在PyQt5应用程序上生成绘图
我想知道Matplotlib绘图在PyQT5桌面应用程序上是如何工作的。 我尝试了几种方法以便绘制图形，但没有任何帮助。 我使用了一个打印功能，这样我至少可以知道图形是打印出来的。它按打印方式打印，但不显示图形。这里需要帮助。下面是我的代码Python 我无法使用MatplotLib在PyQt5应用程序上生成绘图,python,matplotlib,pyqt5,Python,Matplotlib,Pyqt5,我想知道Matplotlib绘图在PyQT5桌面应用程序上是如何工作的。 我尝试了几种方法以便绘制图形，但没有任何帮助。 我使用了一个打印功能，这样我至少可以知道图形是打印出来的。它按打印方式打印，但不显示图形。这里需要帮助。下面是我的代码 ''' Created on Oct 8, 2018 @author: kjohn ''' from PyQt5 import QtCore, QtGui, QtWidgets from PyQt5.QtWidgets import QApplicatio

首先，您为matlabplot创建了一个

绘制输入数据

gridlayout = QGridLayout()
self.setLayout(gridlayout)
self.figure = plt.figure(figsize=(5,5))

self.toolbar = NavigationToolbar(self.canvas,self)
gridlayout.addWidget(self.canvas,1,0,1,2)
gridlayout.addWidget(self.toolbar,0,0,1,2)
最后，Matlabplot小部件应该添加到主小部件布局中
self.matplot = MatplotlibFigure()
self.verticalLayout.addWidget(self.matplot)
Matplotlib.pyplot
用于获得更好的图形，甚至可以使用不同的样式自定义绘图
